Intelligent power source (New model) by whole digital microprocessor control bases on the digital TDW 2500MB welding machine is a series of products of TDW3000MB pulse TIG welding machine, input 1~220VAC/50Hz, TIG welding rated maximum welding current 250A, MMA welding rated maximum welding current 200A. Power input : 3 phase 220V is optional for all TD-Series welding machines.
Main characteristics:
The TDW 2500MB welding machine has all the functions of the TDW 3000MB pulsed TIG welding machine: in the argon arc welding state, it can perform stable welding operation with a welding current of 5A and have the simple TIG welding function in the state of MMA welding mode. The low-load voltage output, line energy monitoring related functions etc can be set in the state of MMA welding.
